Ok if you are beginner it really doesn't matter what resort you pick, as long as conditions are acceptable. At this point I would choose something that it's the most affordable to you (unless you have lot of $$$, in that case go to Whistler, BC).

As for 10 days of lessons that seems an awful lot to me. this is what I recommend a couple of days of lessons and see where you stand after those days. If you feel that you need more time with instructors go ahead and do it, if not, go out there and have some fun. 10 days are a lot of riding, enough to give you a feel of what you're going to enjoy the most and a lot of time to improve on your own. You could even take an intermediate course towards the end of your trip to correct your ridding.
